Advisory, Option or Contingent Measure in the United States:

*Ann Arbor (MI), New York (NY), Yonkers (NY) and Cary (NC) have used IRV in the past.

**Cambridge (MA) uses a similar ranked
voting system for its city council elections, but it is the choice voting
method of proportional voting where each of the nine winners needs a
little more than 10% of the vote. Davis (CA) passed an advisory measure
in 2006 in favor of this system.
